12 claims. (onse- 115) This invention relates to vnew and usefulimprovements 2,810,245 Patented Oct. 2,2, 1957 in machines for insertingindividual lengths of fibrous maare disclosed and claimed machines ofthis general type in which a strand of fibrous material such as cottonwadding is fed in individual lengths into the necks or tops ofsuccessively presented, continuously moved bottles. f

A machine constructed in accordance with this invention is animprovement over those disclosed and claimed 4 in the above patents,particularly with respect `tothe provisions for compacting the cotton inthe necks of the containers by providing means includingreciprocable andoscillatable tucker fingers which act to lrotate the iny dividualstrands of cotton and thereafter to push downwardly on the strands atvarious arcuate positions and thereby to effect a compacting andcomplete insertion of each strand. Improved means are also 'provided forpreventing the feeding or parting of individual lengthsof brous materialwhen no bottle is in position to receive them. f

It is, therefore, anvobject of this invention to provide a machine forthe insertion of fibrous materials into partially filled bottles inwhich individual lengths are first separated from a continuously fedstrand of fibrous material, then rotated slightly by tucker fingers toalign the individual length with the major cross-sectional axis of abottle, which ngersare thereafter effective to insert the strands intosuccessively presented bottles and to compact the strands in the necksof the bottles by successive poking actions at various arcuatepositions.y

Another object of this invention is to provide a machine of thecharacter stated having a reciprocable and rotatable set of tuckerfingers which are arranged to act in fixed and definite sequence tocompact cotton into the necks of successively presented bottles.

A further object of this invention is to provide a machine of thecharacter stated which is capable of continuo'usly inserting andcompactly positioning individual cotton strands into the necks ofsuccessively presented bottles.

' A further object of this invention is to provide a machine of thecharacter stated which is simple in design, rugged in construction andeconomical to manufacture.

The various features of novelty which characterize the invention arelpointed out with particularity in the claims annexed to and forming apart of this specification. For a better understanding of the invention,its operating advantages and yspecific objects attained by its use,reference should be had tothe accompanying drawings and scribed apreferred embodiment of the invention.

Fig. 18 is a fragmentary vertical section taken lalong the line 18-18 ofFig. 3. g h Referringtothe drawings in detail, the invention asillustrated is embodied in a single station machine for insertingindividual lengths of fibrous strand into par# tially filled bottles andincludes a base A, brous material and strand-separating and -feedingmechanism generally indicated at B, a turret assembly generallyindicated at C and performing the material inserting operations, adriving mechanism generally indicated at D, an intake and dischargeconveyor generally indicated at E and a container generally indicated atF which holds a Vsupply G of unbroken, stranded, fibrous material suchas cotton.

The drive mechanisms include a motor 10 mounted on 'a base 12 which isadjustably positioned on one end of the turret C and is connectedthrough a belt drive 14 and spiral gears 16 to a shaft 18. The rotativespeed of the shaft 18 through the belt 14 maybe adjusted by varying theangular position of the base 12 through the use of a liandwheel 20providedfor that purpose since the motor 10 is provided with .-avariable pitch drive pulley. The shaft 18 is mounted in suitablebearings on a lower spindle plate 22 and an upper spindle plate 24 whichin turn are adjus-tably affixed to a main spindle 26 having its bottomportion threaded. The lower spindle plate 22 has a lower hub or sleeveportion which bears against a thrust bearing 28. The thrust bearing 28is carried by the upper portion of a sleeve 30 which is threaded on thelower end of themain spindle 26 for vertical adjustment therealong.

A hollow shaft 32 having a lower Veccentric portion 33 isv positionedftorotate around'the spindle 26 between the lower spindle plate 22 and theupper spindle plate 24 and is spaced kfrom the latter spindle plates byan upper washer 34 and a lower washer 36. The vertical position of theupper and lowerr spindle plates 22 and 24 and the hollow shaft 32 may bevaried by adjusting the position of the sleeve 30 `on the yspindle 26. Acylinder cam 3:8,fhaving a central hub which is affixed to the Vhollowshaft 32 as by set screws and normally rotates therewith, is providedVwith gear teeth around the lower periphery thereof which mesh ,withradriving gear 40 'affixed to the shaft 18. The shaft 18 is provided witha thrust bearing 42 positioned `@erogata alzare th 44 Sfcufed .t the1.9A4 may be used to operate the up or adjustment purposes.eiflietlousalerudle platerzzgsxtends latera11n-and-route, wfdlyleyqadtheuprsrrindlePlateaaridlis prey 'de dz with suitable bearings to hold anindexings11,aft46;1f1fhe shaft 46 is indexed or rotated90j,atlinteryalsby means of `an eccentric pivot-arm andratchet;farrangement.l This arrangement includes Kay strap 48 securedaround the eccentric 33 ofthe hollow shaft 32 and connected to themedial portion of an arm A50 `.which in is pivoted4 at one end to a stud51 fastened to the lower spindle plate 2,2:and pivotally connected atits other end to ODG end'of a link 52 havingits other end pivotallyconnected to allllbbed plate 54which is oscillatably mounted on `theupstanding hub ofa ratchet 60 keyed to the shaft 46 and is provided witha detent arm or pawl 6 which is biased inwardly toward the shaft 46 by aspring 58. The pawl 56 is arranged to engage ,one of four equally spacedteeth ,along the periphery of the ratchet 60. The `hubbed plate 54 isheld in place by arnut 62` threadably engaged with the ratchet hub. Thearm 50 is oscillated by the eccentric 33, resulting in reciprocation ofthe link 52 to cause the pawl 56 to engage one of the recesses on theratchet` 60 and to index the shaft 46 through a90 arc during each 360rotation of the eccentric. On the lower portion of the hubbed plate 60is a friction-faced brake plate 64 which is biased upwardly by a spring66, the tension on which may be increased or decreased by means of-anadjustably positioned nut 68 which is threaded on to the lower` portionof the hubbed plate `60. A friction washer 69 is interposed between thelower spindle plate 22 and the ratchet 60. The brake plate 64 and theratchet 60, under the influence of the spring 66, together act as abrake Vto prevent rotation of the shaft 46 except when an indexing'movement is taking place.

Intake star wheels 70, 70 are rigidly affixed to the lower end of theshaft 46 and are provided with four bottle'- receiving pockets whichreceive bottles in succession from the conveyor E in operativeassociation with the mechanism of the turret C. A circular disc 90 issecured to the` hereinafter to stop the feeding of cotton whenever thereare no bottles being fed-to the star wheels.

The continuous strand of cotton wadding -is` adapted to be withdrawnfrom its container bythe feeding mecha-N nisms B which are carried by-and driven from `the depending hub of the ratchet 60. -For this purposea large driving gear 76 is secured to the depending hub of theratchet 69and meshes with a small pinion 78 which is freely .ro-

tatable about an upstanding stationary spindle 80 mount-` ed on a cover82. A pentagonal plate 84 (see FigmS) having a suitable aperture to passaround the spindle 80 is secured beneath the lower lip of the cover82.'r rIlhe spindle 80 also carries la gear 86 underlying thepinion78which ispin-connected to the pinion in order to rotate therewith.

.The gear 86 meshes with a gear (not shownlmounted on the upper part of4a vertical shaft 87 (see Fig. 5) journalled between pentagonal plate 84and a lower rectangular plate 88. Another gear92V is mounted onVtheupper part of the shaft 87 below the aforementioned gear. which isnot shown on the drawings, and it meshes with a gear 94 of the samediameter mounted ,on a shaft 96a (see Fig. journalled in bearing blocks96, 96 slidably carried in slots formed in the outer edges ofthe` plates84' an'd 88.

A similar set of bearing blocks 96, 96 are carried in slotsA formed inthe outer edges of the plates` 84 andV 88 in spaced parallel relation tothe first set ofslotsi jTlre blolcks elower .Spindlqplatezl andvwithahandwheel A dpttbasbaftlmhillz ine manually for start-` 96are yieldablyretained in the slots by a yoke 98 and an v.slilltalblecmupressionspring 100.`

A shaft (not shown) is Yjournalled in the rear set of the bearing blocks96 and Visprovided at its upper end with `a gear 104 which is the samediameter as and meshes with a gear 106 xed on a shaft 108 journalled inbearings in the plates 84 and 88." 1;

A knurled` or fluted feed roll 110 is affixed to the` shaft 108 betweenthe plates 84 and 88 and cooperates with a similar feed roll 112 aixedto a shaft (not shown). The rolls 110 and 112 constitute the rear pairof feed rolls and are intermittently stoppable, as will be hereinaftermore fully described. Knurled or fluted feed rolls 92a and 94a are alsoaffixed to the same shafts that carry the gears 92 and 94 as shown inFig. 10. These rolls cooperate to constitute the forward pair of feedrolls and are continuously driven by the gear 86. The forward feed rollsare oriented with the rear feed rolls 110 and 112 to dischargecotton'tangentially to the star wheels 70, 70. s Means are providedtointermittently stoprotation. of the rear pair of feed rolls 110 :and112 while permitting the forward pair to continue to rotate and thereby`to effect the parting or separating of individual lengths of cottonwadding from the strand lthereof solely through tension. vThese meansinclude a freely mounted gear 114 which is rotated by the gear 86 andacts to `rotate the shaft 108 and gear 106 affixed thereto beneath thegear 114 through the medium of friction washers 118 and 120 a clutchmechanism. The clutch mechanism includes a hubbed driving plate 122which is biased downwardly by a spring 124 secured to theshaft 108-by abolt 126 and washer 128. The

' driving plate 122 exertsdownward pressure through a friction washer130, gear 114 and friction washer 118 to rotate the shaft 108 andthereby the gear 106 which meshes with gear 104 so as to cause rotationof the rear feed rolls 110 and 112.` The parting of the cotton intoindividual lengths will be effected by lifting the driving plate 122 adistance sufficient to relieve driving pressure onthe washers and gearstherebelow so as to cause the rear feed rolls to stop while the forwardfeed rolls pull the cotton apart. To disengage and stop the drivingplate v 122 there is provided a friction washer 132 and a hub frictiondisc 134 which are cam-controlled. ,f

A cam generally indicated at 136 regulates the position of the drivingplate 122. The cam acts througha mcchanism including an; arm 138provided at its inneryend "T" with a hubw140 whichjis pivotally carriedby anupstandingstud 141. `The outer end of the arm 138 is provided withan upstanding boss 142 which comprises an-upwardly extending roller camfollower 144. Another arm.`

146 rigidly `connected to the arm 138 through the medium o f the hub andextending in a generally opposite direction therefrom is provided at itsouter end witha transversely disposed pin or stud 148 threadably en-kgaged therewith and having a flat outer end adapted to exert pressureupon a ball secured to a depending arm 150 of a bell crank 152. The bellcrank 152 is pivoted on a shaft 153 held in place on a mounting aixed tothe upper end of the stud 141. The other arm of the bell crank 152comprises a yoke which spans the hub of the friction disc 122 andengages the underside of the disc portion thereof. 152 extends across apair of fiats (not shown) on the friction disc so as to prevent rotationthereof during the periods when the rear feed rolls 110 and 112 arestopped.

y In the driving position the driving plate 122 is down and the camfollower 144 rides around the cam 136 on the low portion thereof. When ahigh spot is reached the cam follower is moved out and through themedium ofthe arms 138 and 146, the stud 148 and the bell crank 152', andcauses the friction disc 134 and the friction washer 132 to bear againstthe clutch drive plate 122 to move it .upwardly along the shaft108 andthereby stop The yoke portion of the bell crank` its rotation and therotation of the gear 106, the latter no longer being held tightly by thewashers 118 and 120. It will be noted that the drive plate 122 isdrive-connected tov the shaft 108 through the medium of a keyway andball keys indicated at 154'which permit axial movement of the drivingplate along its associated shaft. The gear 114 will then be permitted torotate freely between the washers 130 and 118 without driving the gears106 and 104 and the associated feed rolls 110 and 112. The cam 136,shown in detail in Fig. 8, comprises an arrangement of three discs, eachhaving equal high, medium and low peripheral arcs which may be rotatedwith respect to each other to change the effective contour over whichthe follower 144 will travel. ln addition, a disc 156 is provided toblock out the low portions of the cam when no bottles are being fedthrough the machine so as to completely cease the operation of the rearfeed rolls and thereby to stop the feeding of the cotton.

The disc 156 carries a stud 158 ball-joint connected to one end of alink 160 the other end of which is pivotally connected to an arm 162affixed to a square-shanked rock shaft 164. A spring 166 is connected toan arm 168 mounted o-n the square-shanked rock shaft 164. An arm 170 isslidably carried by the rock shaft and is pivotally connected to one endof a link 171 having its other end connected to a stud 173 which has itsupper end pivotally connected to the half annular ring 72 and its lowerend extending through an enlarged aperture 173a formed in the underlyingplate (see Fig. 17). One end of the half annular ring 72 normally ispositioned adjacent tlie bottles feeding along the conveyor E to thestar wheel 70. When no bottles are present, however, the half annularring 72 is caused by the action of the spring 166 and the arm 170 tomove toward guide rails 172. This in turn causes movement of the link160 which results in the positioning of the disc 156 so as to presentonly a high portion of travel for the cam follower.

The cotton leaving the forward feed rolls comes into operativeassociation with mechanism carried by the turret C for rotating thecotton 90 and then inserting it into the necks of bottles presentedtherebeneath by the movement of the star wheel 70 and compacting thecotton therein through successive reciprocating and oscillatingmovements. The cotton exiting from the forward feed rolls comes againstan angular stop 174 supported on a plate 175 secured to the plate 84.The stop is constructed to deflect the cotton to one side so as toinitiate its rotation of 90. A counterweight 176 is secured by a link178 which is clamped to a stud 180 projecting below the turret C.Another arm 182 extends from the counter-L weight to the cover 82 andmay be adjustably positioned so as to move the counterweight 176 tobalance the feeding mechanism which is supported by the shaft '46.

In accordance with the invention there is provided a pair of tuckerfingers 184 which depend from the bottom of a cylindrical sleeve 186journalled between the upper and lower spindle plates 24 and 22. Thesleeve 186 is provided with a cross-head 188 having a projecting portionwhich terminates in a roller follower 190. The follower 190 engages thecylinder cam 38 to effect reciprocation of the sleeve 186. Thecross-head 188 is provided with a thrust bearing 191 on the upperportion thereof which surrounds the sleeve 186 and carries the thrust ofa bearing collar 192 positioned thereabove and affixed to the sleeve186. The cross-head 188 is urged downwardly by a pair of springs 194which are carried on a pair of spindles or rods 195 which extend througheach arm of the cross-head 188 and are secured to the upper spindleplate 24 and extend downwardly through the lower spindle plate 22. Thesprings 194 bias the cross-head downwardly to maintain the rollerfollower 190 in contact with the cylinder cam 38. A bracket 196 isfastened to the top side of the spindle plate 24 and is provided with avertical rod 198 which extends downwardly therefrom into the inside ofthe sleeve 186. The lower end of the rod 198 is provided with acylindrical plug which forms an abutment for the upper end of acompression spring 200 which is carried withinI the sleeve 186 in orderto bias the sleeve downwardly and urge the bearing collar 192 intocontact with the thrust bearing 191 of the cross-head 188. Thus thesleeve 186 may be urged upwardly independently of the position of thecam follower 190 on the cam 136 whenever sufficient resistance isencountered to overcome the tension on the spring 200.

Means are also provided to oscillate the sleeve 186 through definiteangular movements. These means include a cam 202 which is affixed to ahub 204 which is secured to the sleeve 32. The cam actuates a rollerfollower 206 which is fastened to the mid-portion of an arm 208. The arm208 is fastened at its inner end to a vertical rock shaft and isprovided at its other end with a gear sector 209 which meshes with arelatively thick gear 210 rotatably mounted on one of the spindles 195which in turn meshes with a pinion 212 affixed to the sleeve 186. Thearm 208 is biased so that the cam follower 206 is maintained in contactwith the cam 202 by means of a spring 214 fastened to an arm 216 whichis fixed to the arm 20S at its pivotal'point.

The operation of the tucker fingers under the influence of the cam 38and the cam 202 results in the reciprocation and oscillation of thetucker ngers 184 as shown by Figs. 10 to 15. Cotton leaving the forwardfeed rolls is deflected to one side by the stop 174 as it becomessupported on the plate 175, and as the mid point of the cotton strandllength moves into registry beneath the tucker fingers 184 the fingersmove downwardly to engage the cotton and to bodily rotate it clockwiseThis 90 rotation is necessary to lbring the longitudinal'axis of thecotton strand into'alignment with the major cross-sectional axis of thecontainer. In `this position the cotton is centered over a hole providedtherefor in the plate 175. The tucker fingers move downwardly under theinfiuence of the cam 38 tol effect an initial tucking of the cotton (seeFig. 12). The fingers then move upwardly and under the influence of thecam 38 are rotated45 counterclockwise. A further ing action is theneffected by the action of the cam 38. Thefingers again move upwardly andare then rotated 90 clockwise under the influence of the cam 202followed by another ing action. The tucking fingers then move upwardlyand are then returned to the starting position by bein-g rotatedcounterclockwise to complete one full cycle.

It is, of course, to be understood that various details of arrangementsand proportions of parts may be modified within the scope of theappended claims.
